Application filed September 1, 1909. Serial No. 515,630.

To all whmn it may concern:

Be it known that I THOMAS M. Cons, a citizen of the United States, residing at Conway, county of Taylor, b'tate of Iowa, have invented certain new and useful Im' provements in Doors, of which the following is a specification.

My invention relates to that class of doors which lie, when closed, flush with the wall or side of the structure to which they are applied, and which are opened by two movementsfirst, bodily, outward from the side of the structure, and secondly, a sliding movement backward, in a plane parallel with the sides of the structure;

The object of the invention is to provide a door ofthis class with operating means of simple and novel construction, and positive and easy action.

' 'With these objects in view, my invention consists of the novel construction and arran ement of parts as hereinafter fully descri d, particularly pointed out in the glaims an illustrated in the drawings.

In said drawings-Figure 1 is a side elevation of a portion of a structure, showing a I door applied thereto constructed in accordance with this invention. Fig. 2 is a vertical sectional view on line 2-2, Fig. l, the door being in closed position; and Fig. 3 is a similar view, showing the door in open position. Fig. 4 is a detail view of certain parts of the'invention shown in Fig. 1.

A desi ates a. sliding door fitted to an o ening in the side of the structure B. To t e door, at suitable distances from the front and rear thereof, are journaled two rock shafts C and D. These rock shafts are securely held to the door by means of bearin clips e in which they are free to turn. Eac rock's aft is'provided at its u er end with an L-sha d crank bend d. e continuation of t e vertical arm or portion f of the crank bend is-bent downwardly and passes into a vertical recess or bearing gj formed in each hanger G by which the door is suspended. These hangers are provided with rollers, and are adapted to move upon, the upper track H; They may be of any ordinary or suitable construction; The lower end of each 'extending downwardfrom the horizontal shaped rtion and engagin the lower track H, as ereinafter describe Thus far the noted that the vertical portion f of the u arrangement specified is not broadly new with me.

At approximately midway its length, each rock shaft is bent, first, in a horizontal plane. for a short distance, then outwardly to am 0b a substantially U-shaped seat i' the whole forming a crank I. A bar K, extends item the door and rests in the seats 5', i of the rock shafts, bein pivotall connmteti there to 'by means of Treating c i ps Fig. 1. The function of this ar isto operate the rock shafts throu h the inseam tality of the crank and time efie'ctuateithe' opening and closin movements of the door;

To the rear end 0 the bar K is ivotaliy 7h attached an arm or extension L. his arm projects beyond the rear end of the door,- and is bent outwardly at l as shown in a When the door is in'closed position, me end of arm K projects a ainst a etc or post 73. M, sehured to the door lacinger ot er tion bf the buildin adjoining the The arm is held firml against the door and facing by a spring M attached to the door. This arm L serves a two-fold function, as will hereinafter a pear.

When the door is closed, the parts will lie in the position shown in Fig 2. The portions it and 2' of the lower crank-shaped ntion of each rock shaft lie in thesame p one as the door; while the horizontal ortion f of the upper crank bend of each roek' shaft exten s outwardly and backward in an oblique line from the door. It will be or crank-bend does not fit close to t anger, but extends outward for a short distance. This is necessary in the construction illustrated for the reason that the outward movement of the bar K swings the vertical portion fbackward until (at the extreme outward position of the door? it rests'against the hanger, as shown in ig. 3., However this may be obviated b passing the yerticalportion f u ward t roufgh the hanger, and securin it y means 0 a bolt or other device, whi e at the same time leaving it free to rotate therein.

The door is operated as follows: With the parts in the position shown in 1 and 105 2, the bar K is ulled outwardly, us turning the cranks? I, in the seats ofcwhich it rests, in a direction toward the rear of the door. This movement, b means of the upper and lower crank-hen s, carries each rock 11 as shown' invts shaft, and consequently the door attached thereto, outwardly, until the door has advanced sufiiciently to clear the walls of the structure. bearing points of the lower crank bends, the

door, while moving out-ward, is siinultaneousl given a backward movement, causing the angers to slide upon the upper track, and giving a slight backward momentum to the door, which greatly aids the operator in immediately sliding the door backward 1 to expose the opening. 'lhebar K in its outwardmovement, carries with it the arm L, thus enabling the latter to clear the stop or post M. On the return movement of the door, the latter slides along the upper track until it reaches a position a little to the rear the opening 6, whenits further forward movement is prevented by stops which contact with the per forward hanger and the or- 'tionc' pf t e lower forward crank beu as shown. At this point, the base of the outwardlyturned portion Z of the arm L, rests on the stop or post M, as shown in 'Fig. 4.

u 26 163w when the bar K is pressed inwardly, this portion Z of the arm comes into contact with the bar, thus aiding the rock Owing to the position of the {fastened to the structure to which the door is applied, and thus act as a fastening means E for the door.

Letters Patent is p 1. In a device of the character described, a sliding door; rock shafts jo'urnaled therei to, said rock shafts being bent, intermediate their length, twice in a horizontal plane at- I right angles to each other, and the last bend i; and an operating bar fitting in and secured to said crank seats, substantially as described.

a sliding door; rock shafts journaled to said door; cranks formed in sald rock shafts intermediate their length; an operating bar out turned portion l adapted to engage a post M and exert a pressure upon the end of closed position, substantially as described.
